I must be missing something. I tried this. (Windows, IDLE, Python 2.5)
# Try each module
import sys
import numpy
import scipy
import string
dependencies = "numyp", "scipy"
for dependency in dependencies:
try:
__import__(dependency.name)
except ImportError:
# Uh oh!
dependency.installed = None
else:
# The module loaded OK. Get a handle to it and try to extract
# version info.
# Many Python modules follow the convention of providing their
# version as a string in a __version__ attribute.
module = sys.modules[dependency.name]
# This is what I default to.
dependency.installed = "[version unknown]"
for attribute_name in ("__version__", "__VERSION__", "VERSION",
"version"):
if hasattr(module, attribute_name):
dependency.installed = getattr(module, attribute_name)
break
The result was this.
Traceback (most recent call last):
File

__import__(dependency.name)
AttributeError: 'str' object has no attribute 'name'
